Re: MSP430F5528 - Clock and UART

If he's setting up the FLL right he should be fine. I've never used the 
parts with FLL, but on other parts I can get reliable 460kb comms with 
just the occasional tweak if temperature drifts too much, using a watch 
crystal and the internal calibrated DCO data. The FLL is supposedly more 
accurate than the calibrated DCO, but of course it depends on the 
accuracy of the watch crystal to start with. I still think 115.2kb 
should be easy, especially using the UART hardware and ints.
